Description

Technical Field

[0001] The invention relates to the technical field of hinge devices, and in particular to a slowly self-locking gas spring hinge. Background Art

[0002] At present, ordinary hinges are widely used as hinges for building doors and windows. Existing doors and windows are mainly opened and closed in two ways. The first is to use traditional folding hinges, but this hinge only has a hinge function. When users close the door casually, they usually need to push one side of the door to move toward the door frame. This can easily cause excessive force to cause the door and door frame to collide too loudly or produce a huge impact between the door and door frame, which will reduce the service life of the door. The second is to use a combination of ordinary hinges, door suction and door closers. This method occupies a considerable proportion in the building hardware industry. First, install a door suction at a specific position on the ground or wall. When opening the door, when the door is opened to this angle (generally 90°), use the door suction to fix the door. Then install a door closer at the upper end of the door frame so that the door can be automatically closed within this specific angle range. This combination has the problems of complex installation, large space occupation, and more materials; and the door closer has a short life, requires a large force when opening the door, and there are problems such as oil leakage, which does not meet the humanized design.

[0003] The hydraulic hinge was disclosed on 2016-06-15, with the publication number CN205314750U, and includes a door frame fixed hinge and a rotating hinge, wherein the door frame fixed hinge is fixed on the door frame, and the rotating hinge is fixed on the door, wherein the door frame fixed hinge and the rotating hinge respectively have a lower accommodating barrel and an upper accommodating barrel, wherein the upper accommodating barrel and the lower accommodating barrel are separated by a plane bearing, and the top of the upper accommodating barrel is sealed by an upper end cover, wherein the upper end cover has a plurality of columns, and the upper accommodating barrel has a mandrel and a coupling sleeve inside, and the mandrel has a plurality of arc holes, through which the columns pass, and the upper end cover and the mandrel are combined together by a first speed regulating screw, and the upper accommodating barrel and the mandrel are fixed by a fixing pin. The hydraulic hinge of the present invention plays a damping role through hydraulic pressure, and can make the door close and open slowly without generating a loud noise, and plays a positioning role when opening the door through the internal positioning pin.

[0004] However, hydraulic hinges still have certain shortcomings during use. After a period of time, hydraulic hinges are prone to oil leakage, which affects the use effect. At the same time, the overall manufacturing cost of hydraulic hinges is relatively high. Summary of the invention

[0005] The purpose of the present invention is to solve the problems raised in the above background technology and to propose a slow self-locking gas spring hinge.

[0019] The gas spring pushes the driving rod and the sliding rod to move, the sliding rod and the slideway limit and squeeze each other, and the rotation of the rotating sleeve drives the swing leaf to rotate.

[0020] Furthermore, a bearing is symmetrically connected to the second connecting portion, and the bearing is rotatably connected to the first connecting portion.

[0021] Furthermore, a limiting surface is arranged on the side wall of the rotating sleeve, and a plurality of groups of limiting surfaces are evenly distributed on the rotating sleeve. A track groove is opened in the second connecting portion, and the limiting surface matches the track groove.

[0051] It should be noted that the gas spring part 3 is a gas spring available on the market, and the driving source of the gas spring is helium.

[0052] A driving rod 301 is connected to the driving end of the gas spring part 3, and a connecting buckle 3011 is fixedly connected to the end of the driving rod 301 away from the gas spring part 3, and a sliding rod 3012 is fixedly connected to the connecting buckle 3011. A slideway 901 is provided on the rotating sleeve 9, and the sliding rod 3012 is placed in the slideway 901, and the sliding rod 3012 and the slideway 901 match;

[0053] The gas spring 3 pushes the driving rod 301 and the sliding rod 3012 to move, the sliding rod 3012 and the slideway 901 are mutually limited and squeezed, and the rotating sleeve 9 rotates to drive the swing leaf 2 to rotate.

[0054] The second connection part 201 is symmetrically connected with a bearing 6 , and the bearing 6 is rotatably connected to the first connection part 101 .
